THEODORE SAMUEL BINDSOHEDLER, OF PERU, ILLINOIS, ASSIGNOR TO THE WESTERN COMPANY, OF LA SALLE, ILLINOIS, A CORPORATION OF WATCH-B ARREL.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed August 20, 1906- Serial No. 331,346.

To all whom it may concern:

Be it known that I, TnEononn SAMUEL BINDsenEn- LEE, a resident of the United States, in the city of Peru, county of Lasalle, and State of lllinois, have invented a new and useful improvement in Watch-Barrels, of which the following is a specification.

My invention relates to improvements in watch barrel arbors and has for its object the production of an arbor the parts of which are simple, easily manufac tured and assembled, and when assembled tends to keep the coiled spring in the barrel parallel to the side of said barrel and to the time main wheel, enabling them to run very close to each other. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which:

Figure l is an end view of a watch winding mechanism, Fig. ll is a sectional view of Fig. I showing my invention, Fig. lll is a sectional view of the barrel, showing the journals of the barrel arbor, Fig. 1V is a front view of F ig. Ill, Fig. V is a front view of the member of the barrel arbor which is fastened to the time main wheel, Fig. V1 is a sectional view of Fig. V.

Similar figures represent similar parts in all the drawings. V

in the drawings, 1 represents the front plate and 2 represents the barrel bridge of an ordinary watch.

3 is an arbor which is rigidly fastened to the winding barrel 8 and iournaled in the front plate 1 and barrel bridge 2.

4 is the main wheel, which is rigidly fastened to the cylindrical member 5, which carries a projection or hook 6 by means of which it is fastened to the main spring 7. This cylindrical member 5 has an aperture 11 (see Fig. VI) by means of which it is journaled on the arbor 3. The winding barrel 8 has teeth 9 by which it is rotated and stopped by any of the usual means.

10 is a pin in barrel 8, to which the outer end of the main spring 7 is fastened. The arbor 3 has a shouldered part which is of the same diameter as the cylindrical member 5, which tends to keep the main spring 7 parallel with the inside surface of the barrel 8 and with the main wheel l.

It is evident that the parts of my invention are'simple, readily made, easy to assemble and inexpensive and that the main spring will always be parallel with the inside surface of the barrel and with the main wheel, which enables these parts to be put together very near each other, which is a valuable feature in reducing thickness of watches.

I claim:

A watch barrel comprising the followingseparablv lornierl elements: a shouldered arbor, a winding barrel.
